\(\frac{1}{2}\cdot\frac{2}{3}\cdot\frac{3}{4}\cdot\frac{4}{5}\cdot\frac{5}{6}\)

Answer 1

\(\frac{1}{2}\cdot\frac{2}{3}\cdot\frac{3}{4}\cdot\frac{4}{5}\cdot\frac{5}{6}=\frac{1\cdot2\cdot3\cdot4\cdot5}{2\cdot3\cdot4\cdot5\cdot6}=\frac{1}{6}\)

Answer 2

\(\frac{1}{2}.\frac{2}{3}.\frac{3}{4}.\frac{4}{5}.\frac{5}{6}\)

= \(\frac{1.2.3.4.5}{2.3.4.5.6}\)

= \(\frac{1}{6}\)

Answer 3

\(\frac{1}{2}\times\frac{2}{3}\times\frac{3}{4}\times\frac{5}{6}=\frac{1.2.3.4.5}{2.3.4.5.6}=\frac{1}{6}\)
